Provides a liquid base for a product.

Sodium HypochloriteBleach

Sodium hypochlorite is the basic ingredient in laundry bleach and mold and mildew stain removers. It is also a bleach that helps to break down drain clogs.

Proprietary Surfactant BlendCleaning Agent

For competitive reasons, the supplier of this cleaning agent (surfactant) has asked us to keep the details confidential, and we're legally bound to do so. But we can tell you that it's a cleaning agent (or blend of cleaning agents) that we use in our products to remove dirt and deposits by surrounding dirt particles to loosen them from the surface they're attached to, so they can be rinsed away.

Sodium HydroxideCaustic

Sodium hydroxide is a builder that can also be found in detergents and degreasers. We use it to make a product formula clean better by affecting the molecules in the formula so they work together better. Sodium hydroxide can also be a pH adjuster that alters the pH of a product to improve stability. Every formula has an optimum pH to make it work best. For example, a formula that’s more acidic works better for soap scum removal. Its opposite, a formula that’s more alkaline, might be more effective at removing grease or greasy soils. We use pH adjusters to make sure we achieve the best pH for a particular job. Also, the pH of a formula can affect how long it lasts within a container – for example limiting its tendency to corrode a can, container or dispenser. In high concentrations (such as in drain cleaners), sodium hydroxide can also be used as a caustic that helps dissolve organic matter like drain clogs.

Sodium SilicateCorrosion Inhibitor

Sodium silicate is a corrosion inhibitor that can also be found in laundry detergents, dishwashing detergents and hard surface cleaners. We use it in our products to help keep metallic household surfaces such as faucets and drains free of corrosion.

NEW! More Fragrance Disclosure

SC Johnson is the first major company to offer product-specific fragrance disclosure. We started with air care products in the U.S. and Canada, and we'll be adding other product categories soon.

Our goal is to list all ingredients down to .09 percent of the product formula. If that doesn't provide at least 10 ingredients, we will list the top 10 if there are at least 20 fragrance ingredients present.

We will always try to select the method of disclosure that gives you the longest list and the most information.

While they aren't disclosed, the remaining ingredients also must meet our strict standards and be approved as part of our fragrance palette in order to be used. You can learn more about our palette here.
